Abstract (en)

[origin: EP3843463A1] An IAB donor is properly grasped. A radio communication apparatus according to one aspect of the present disclosure includes a transmitting/receiving unit that communicates with an integrated access backhaul (IAB) node, and a control unit that determines whether or not the IAB node has a function of an IAB donor based on a predetermined signal or channel received from the IAB node.
